Key Information:

• Six years after the first commit, LiveView 1.0 is here, offering a dynamic server-rendered approach without JavaScript.
• It provides real-time form validations, shopping cart updates, and more with a server handling rendering and dynamic updates.
• The programming model is optimized with a diffing engine that splits templates, reduces payloads, and sends only partial diffs.
• LiveView has best-in-class latency due to stateful connections and fewer round trips.
• HEEx components with HTML awareness and compile-time checking enhance composability.
• Streamlined HEEx syntax and markup annotations improve development workflow.
• Interactive uploads and streams/async primitives handle large collections and async operations.
• LiveView is gaining popularity in various programming communities.

Important Details:

• The initial concept was to run UI on the server like in React.
• Phoenix Channels scale to millions of connections.
• Optimizations include fingerprinting, for comprehensions, and tree sharing.
• HEEx components have slots for extensibility.
• Interactive uploads have drag and drop, progress, and previews.
• assign_async and start_async handle async operations easily.
• new.phoenixframework.org helps start new projects quickly.
• Future plans include collocated JavaScript hooks and more.
• Special thanks to the Phoenix team, especially Steffen Deusch.
